An enhancement is observed in $K_{S}^{0}K_{S}^{0}$ mass spectrum near 1.7 GeV/$c^2$, which was not seen K^+K^-\pi^{+}$ earlier work, implying existence isospin one partner $f_0(1710)$.

In particular, a piecewise function that describes dynamics determined as $M_{\pi^{0}\pi^{0}}$ from an $(1.311\pm0.011)\times10^{9}$ collected by BESIII detector. The goal this to provide description scalar and tensor components $\pi^0\pi^0$ while making minimal assumptions about properties or number poles amplitude. Such model-independent allows one integrate these results with other...
